Effects of pre-and postharvest treatments with potassium phosphite, potassium phosphate, and salicylic acid against the severity of gray mold disease caused by Botrytis cinerea in strawberry fruits were investigated under ambient conditions. Seven B. cinerea isolates were collected from naturally infected strawberry plants. The treatment with potassium phosphite at concentration of 500 mg/L significantly reduced the fungal growth compared to other treatments in vitro. The treatments with potassium phosphite at concentrations of 250 or 500 mg/L resulted in the highest disease reduction, followed by the treatment with salicylic acid. Additionally, effects of postharvest treatments with these compounds on disease reduction and biochemical attributes of strawberry fruits were evaluated during storage for 9 days at ambient conditions. The highest disease reduction percentage was found with potassium phosphite. Besides, the phenolics content and peroxidase activity of potassium phosphate were found to be greater than those of potassium phosphite or salicylic acid. However, a reduction in the total soluble solids, titratable acids, and ascorbic acid contents of fruits was found for all treatment groups at the end of storage period. Based on the obtained results, potassium phosphite and salicylic acid can be recommended as fungicide alternatives for extending postharvest shelf life of strawberry fruits. [ABSTRACT FROM AUTHOR]
